Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shape changeable surgical implants require invasive surgical interventions for adjustments, limiting their adaptability to clinical conditions and repeatability.
Innovation Solution
An adjustable shape changeable surgical implant system utilizing a swelling body that absorbs and releases fluid, combined with a selective receptor and shape control substance, allowing non-invasive adjustments through oral administration of a ligand and hydrophilic or hydrophobic substances to control implant shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive surgical intervention is used to adjust implant shape, then adjustment precision is improved, but patient comfort deteriorates and adjustment frequency is limited
Solution Approach 1:
The patent replaces the mechanical surgical adjustment system with a chemical/biological system. Shape control substances (ligands) bind to receptors on the swelling body, triggering fluid absorption through biochemical interactions rather than mechanical surgical intervention. This substitution eliminates the need for repeated surgical procedures while maintaining adjustment precision.
Solution Approach 2:
The patent introduces shape control substances as intermediaries between the patient and the implant. These substances, administered orally or via injection, mediate the shape adjustment process by binding to receptors and triggering fluid absorption, thereby eliminating direct surgical contact and reducing patient discomfort.
2Shape
If surgical adjustment is performed, then implant shape can be changed, but adjustment time is increased and repeatability is reduced
Solution Approach 1:
The patent replaces time-consuming surgical procedures with rapid biochemical interactions. Shape control substances quickly bind to receptors and trigger fluid absorption, enabling shape adjustments within minutes rather than hours or days required for surgical intervention.
Solution Approach 2:
The swelling body is pre-equipped with receptors that are ready to bind shape control substances. This preliminary preparation allows immediate shape adjustment upon administration of the shape control substance, eliminating the need for surgical preparation and extending the time required for adjustment.
3Shape
If surgical intervention is used for implant adjustment, then shape control is achieved, but patient autonomy deteriorates
Solution Approach 1:
The patent enables patients to self-adjust their implant shapes by orally administering or injecting shape control substances without requiring surgical intervention. This self-service capability empowers patients to control their own treatment outcomes and adjust implant shapes according to their needs.
Solution Approach 2:
Shape control substances serve as intermediaries that patients can easily administer themselves. These substances translate patient intent into implant shape changes through biochemical interactions, thereby enhancing patient autonomy while maintaining precise shape control.
4Reliability
If invasive surgical procedures are used for adjustment, then implant functionality is maintained, but treatment flexibility is reduced
Solution Approach 1:
The patent transforms the implant from a static device requiring periodic surgical adjustments into a dynamic system that can be continuously adjusted through biochemical interactions. The swelling body responds dynamically to shape control substances, allowing flexible adaptation to changing patient needs while maintaining implant functionality.
Solution Approach 2:
The patent replaces rigid surgical adjustment mechanisms with flexible biochemical systems. Shape control substances can be administered in varying doses and frequencies, enabling fine-tuned adjustments that adapt to patient needs without compromising implant functionality.
